Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep hole plate technology, specifically a stable stacked deep hole plate. Background Technology
[0002] In the fields of biological experiments, gene detection, and drug development, deep well plates are core instruments for sample storage, transfer, and processing. Their use often requires stacking multiple deep well plates to save laboratory workspace while ensuring structural stability and sample safety in this stacked state. However, most existing deep well plates employ a single flat plate structure, lacking a specialized stacking adaptation design. Stacking relies solely on direct contact between the upper and lower plate surfaces, making them susceptible to lateral shifting, interlayer slippage, and even tipping over due to uneven stress or minor collisions. This not only results in sample loss but may also affect experimental progress and data accuracy.
[0003] Furthermore, existing deep-well plates have significant shortcomings in sample processing and ease of operation. Some deep-well plates have flat or conical bottoms with obvious sharp edges and dead zones, making it difficult for liquid samples to adhere to the bottom and transfer completely. This is especially problematic for precious samples such as trace amounts of nucleic acids and proteins, where excessive residue directly reduces experimental utilization and detection accuracy. Additionally, deep-well plates lack hand gripping mechanisms on both sides. When handling or adjusting the stacking angle, operators must hold the plate by the edges with both hands, which increases the risk of slipping and dropping the plate, and also makes precise control of the stacking position difficult, increasing operational complexity and experimental risks.
[0004] More critically, existing deep-well plates are prone to adsorption problems due to pressure differences when stacked. Most deep-well plates have a closed flat bottom; when stacked, the plates are in close contact with the worktable surface or the surface of the lower deep-well plate, squeezing out the air between the contact surfaces and creating a pressure difference that causes the plates to adhere to each other. This not only makes it difficult to quickly separate the stacked deep-well plates, but forced separation may also cause deformation due to excessive force, or even damage the samples inside the deep holes. These problems collectively restrict the application of deep-well plates in high-efficiency experimental scenarios, necessitating a deep-well plate structure that combines stable stacking, low sample residue, and convenient operation to meet the dual requirements of laboratory sample processing precision and space utilization efficiency. Summary of the Invention
[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a stable stacked deep hole plate, which solves the problems mentioned in the background section.
[0006] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A stable stacked deep hole plate includes a base plate, a protruding plate, and a plurality of deep hole cylinders, wherein the base plate is integrally formed with the protruding plate and the deep hole cylinders; the area of the protruding plate is smaller than the area of the base plate. The base plate has finger grooves on both sides, a rectangular groove at the bottom, an inlay groove on the side of the rectangular groove, a rubber pad inlaid in the inlay groove, and ventilation holes on the wall of the rectangular groove on the base plate.
[0007] Furthermore, the bottom of the deep hole in the deep hole tube is hemispherical, which can prevent sample residue.
[0008] Furthermore, the corners of the finger grooves are rounded, and five finger grooves are set in an equally spaced matrix, into which the middle and index fingers can be inserted.
[0009] Furthermore, the cross-sectional height of the deep-hole cylinder is flush with the edge height of the protruding plate.
[0010] Furthermore, the area of the rectangular groove is adapted to the area of the protruding plate, which facilitates stacking.
[0011] Furthermore, several vent holes are provided for venting and preventing the base plate from being directly adsorbed.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example like Figure 1-3 As shown, an embodiment of the present invention provides a stable stacked deep hole plate, comprising a base plate 1, a protruding plate 2, and a plurality of deep hole cylinders 3, wherein the base plate 1 is integrally formed with the protruding plate 2 and the deep hole cylinders 3; the area of the protruding plate 2 is smaller than the area of the base plate 1. The base plate 1, serving as the load-bearing foundation of the overall structure, is integrally molded with the protruding plate 2 and the deep-hole cylinder 3, forming an inseparable and stable whole. This interconnected design avoids the problems of component loosening and misalignment that occur in assembled structures during use, ensuring the overall structural strength of the deep-hole plate. On the other hand, the cross-sectional height of the deep-hole cylinder 3 is flush with the edge height of the protruding plate 2, allowing the protruding plate 2 to provide circumferential protection for the deep-hole cylinder 3, while preventing collisions and interference between the upper base plate 1 and the deep-hole cylinder 3 during stacking, and reserving adaptation space for subsequent stacking operations. The base plate 1 has finger grooves 4 on both side walls and a rectangular groove 5 at its bottom. An inlay groove 6 is formed along the side of the rectangular groove 5, and a rubber pad 7 is inlaid in the inlay groove 6. The protruding plate 2 and the rectangular groove 5 at the bottom of the base plate 1 form a "convex-concave" fitting structure, with their areas precisely matched. When stacked, the protruding plate 2 of the upper deep-hole plate can be completely embedded in the rectangular groove 5 of the lower deep-hole plate, quickly completing the initial positioning of the upper and lower layers and preventing lateral displacement during stacking. Simultaneously, the rubber pad 7 is inlaid in the inlay groove 6 along the side of the rectangular groove 5. When the protruding plate 2 is embedded in the rectangular groove 5, the rubber pad 7 will be in close contact with the surface of the protruding plate 2. Utilizing the high friction properties of the rubber material, the anti-slip effect between layers is further enhanced, preventing the deep-hole plates from sliding between layers during handling or storage. The rectangular groove 5 has ventilation holes 8 on its groove wall located on the base plate 1.
[0017] This robust stacked deep-hole plate achieves stable stacking and efficient sample processing through multi-structure collaboration. Its working principle is as follows: The base plate 1, as the core load-bearing component, is integrally molded with the protruding plate 2 and the deep-hole cylinder 3, ensuring overall structural stability and preventing component loosening during use. The deep-hole cylinder 3 stores experimental samples; its bottom is hemispherical, reducing sample residue and improving sample processing accuracy. Simultaneously, the cross-sectional height of the deep-hole cylinder 3 is flush with the edge height of the protruding plate 2, preventing collisions or interference between the deep-hole cylinder 3 and the upper deep-hole plate structure during stacking, providing space for stacking operations. During stacking, utilizing the matching area of the rectangular groove 5 at the bottom of the base plate 1 and the protruding plate 2, the protruding plate 2 is embedded into the rectangular groove 5, quickly completing the positioning of the upper and lower deep-hole plates and ensuring precise stacking. The finger grooves 4 on both sides of the base plate 1 allow operators to insert their middle and index fingers to hold the deep well plate, facilitating the handling of the deep well plate and adjustment of the stacking angle. The ventilation holes 8 on the walls of the rectangular groove 5 allow air to be expelled from the groove when the deep well plate is placed or stacked, preventing the base plate 1 from adsorbing onto the workbench or the lower deep well plate due to air pressure differences. This ensures smooth stacking, disassembly, and daily use of the deep well plate, ultimately achieving the dual functions of stable stacking of the deep well plate and efficient sample processing.
[0018] like Figure 3 As shown, in some embodiments, the bottom of the deep hole of the deep hole tube 3 is hemispherical, which can avoid sample residue. Compared with the flat or conical bottom, the hemispherical bottom has no obvious edges and dead corners, and the liquid sample can flow more smoothly along the arc-shaped inner wall during the experiment. Whether it is mixing after sample addition, transferring after incubation, or subsequent cleaning operations, the amount of sample adhering to the bottom of the hole can be minimized.
[0019] like Figure 3 As shown, in some embodiments, the corners of the finger groove 4 are rounded, and five finger grooves 4 are set in an equally spaced matrix to accommodate the middle and index fingers. First, the rounded corners eliminate sharp edges, preventing operators from being scratched when inserting their fingers, while also improving the comfort of the fingers contacting the groove walls. Second, five equally spaced matrices are set, the number and spacing of which are adapted to the physiological structure of the human hand, ensuring that operators can accurately insert their middle and index fingers into the corresponding grooves without having to repeatedly adjust their hand position for a stable grip.
[0020] like Figure 3As shown, in some embodiments, the cross-sectional height of the deep-hole cylinder 3 is flush with the edge height of the protruding plate 2. As the core component for carrying the sample, if the cross-sectional height of the deep-hole cylinder 3 is higher than the edge of the protruding plate 2, the bottom of the base plate 1 of the upper deep-hole plate will directly contact the top of the lower deep-hole cylinder 3 during stacking. This may not only squeeze the deep-hole cylinder 3 and cause sample leakage, but also damage the fit between the upper base plate 1 and the lower protruding plate 2. If the cross-sectional height is lower than the edge of the protruding plate 2, the protruding plate 2 will form a protruding structure, which will hinder the precise embedding of the rectangular groove 5 at the bottom of the upper base plate 1 and the protruding plate 2.
[0021] like Figure 3 As shown, in some embodiments, the area of the rectangular groove 5 is adapted to the area of the protruding plate 2, which facilitates stacking and allows for proper matching and stacking.
[0022] like Figure 3 As shown, in some embodiments, several vent holes 8 are provided for venting, preventing the base plate 1 from being directly adsorbed, and preventing the seal from being sealed after the gas is discharged.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
